COMBINED flAOK ANlJ CLOTHES DRIER Filed March 39, 1929 Patented Nov. 19, 1929 UNITED STATES PATENT OFFICE COMBINED BACK AND CLOTHES DRIER Application filed March 30, 1929. Serial No. 351,371.

This invention relates to a combined hall tree or rack, clothes drier and curtain stretcher, and the invention has for an object the provision of novel means whereby a hall tree or rack can be expeditiously converted into a clothes drier or curtain stretcher.

It is a further object of this invention to produce a stand or standard having a plurality of combined garment supports and rack arm supports, and to associate therewith foldable rack arms which may be projected from the standard and caused to assume approximately horizontal positions, the said arms radiating from an element which is movable into and out of the standard.

It is a still further object of this invention to provide removable extensions for the rack arms in order that when the extensions are applied to the rack arms, an increased su porting area for garments or curtains may e rovided.

It is furthermore an object to produce a device of the character indicated which will prove attractive in appearance and which will operate efiiciently.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a view in elevation of a device embodying the invention;

Figure 2 illustrates an enlarged detail view thereof, partl in section;

Figure 3 illustrates a detail view of parts of the device;

Figure 4 illustrates a sectional view of the device on the line 44 of Fig. 1, omitting the brackets;

Figure 5 illustrates a sectional view of the head on which the rack arms are mounted;

Figure 6 illustrates a detail view of the upper end of one of thebrackets with a rack arm thereon;

Figure 7 illustrates a view in elevation,

partly in section, of one of the rack arms and its extension;

Figure 8 illustrates a sectional view on the line 8-8 of Fig. 1; and

Figure 9 illustrates a detail view showing the means for holding the device when set for use as a clothes drier.

In these drawings 10 denotes the base of the rack or tree, 11 a hollow standard supported thereon, the said standard having a longitudinally disposed slot 12 merging with a transversely disposed slot 13 near the upper end of the standard.

A plurality of brackets 14, which may be of the general shape of those shown in the drawing, are secured to the standard at or near its upper end and each bracket has a bifurcated upper end, as shown at 15, and the space between the furcations constitutes a seat for a rack arm 16, when the said rack arms are in position to form a drier or curtain support. It is apparent that the brackets may be utilized as hangers for garments, hats, or the like, while at the same time they have the dual function of supporting the rack arms.

In the present embodiment of the invention, two followers or block-like guiding elements 17 and 18 are inserted in the standard and they are connected together by a staff 19 which projects a suitable distance above the upper follower 18. A crown plate or disk 20 is secured on the staff and it has peripheral recesses 21 in which the inner ends of the rack arms 22 are mounted on pivots 23, it being the purpose of the inventor that these rack arms shall assume parallel positions vertically when they are nested to enter the hollow standard, as they are shown in Figs. 1 and 3. The lower follower is provided with a. handle 24 which is intended to move in the aforesaid slots for the purpose of holding the rack in its position shown in Fig. 2, or when properly manipulated, it may move in the slot 12 to a lower position in which it is shown in Fig. 1 where the rack arms are nested in the standard.

The rack arms 22 may have threaded sockets 25 at their outer ends to receive threaded shanks 26 of extension arms 27 to be employed when curtains are to be support- 100 ed and dried, or at other times, according to the requirements in practice.

I claim:

1. In a combined rack and clothes drier,

5 a tubular standard having a vertically disposed slot, guiding means slidable in the standard, a staff carried thereby, a member on the staff, arms pivoted to the member and adapted to assume approximately horim zontal positions and positions approximately parallel with the stafi, means on the guiding member projectin through the slot whereby the guiding mem or is moved vertically of the standard, brackets on the said standard near its upper end and projecting thereabove, and seats on the brackets for engaging the arms whenin approximately horizontal positions.

2. In a combined rack and clothes drier, a

suitably supported hollow standard, guiding means therein, a staff carried by the guiding means, a member carried by the stafi, arms having their ends pivotall mounted on said member, brackets secured to the standard near its upper end and projecting thereabove,

each of the said brackets having a seat adapted to engage an arm when in approximately horizontal position, the said arms being adapted to nest arallel with the staff when the1 stafi is move downwardly in the stand 3. In a combined rack and clothes drier, a suitably supported hollow standard guiding means therein, a staff carried by the guiding means, a member carried by the staff, arms having their ends pivotally mounted on the member, brackets secured to the standard near its upper end and projecting thereabove, each of said brackets having an arm receiving seat adapted to engage the arms when in approximatel horizontal position, the said arms being a apted to nest arallel with the stafi' when the stafl is move downwardly in the standard, each of said arms having a socket in its end, and an extension of said arm having a projection removably fastened in said socket.
